Abstract
A biorenewable thermoplastic, poly(dihydroferulic acid) (PHFA), which is an effective polyethylene terephthalate (PET) mimic is disclosed. The PHFA can be prepared by the self-condensation of acetyldihydroferulic acid as the monomer that can be synthesized from the starting material-ferulic acid, which can be isolated from lignin, rice bran, or other biorenewable sources.
